A novice pool player is faced with the corner pocket shot shown in Fig. 7-49. Relative dimensions are also shown. Should the player worry that this might be a "scratch shot," in which the cue ball will also fall into a pocket? Give details. Assume equal-mass balls and an elastic collision.Ignore spin.
We have to predetermine whether the shot of the player would be “scratch shot” as per the given condition.
Step 1 of 3</p>
Perfectly elastic collision: In a perfect elastic collision, the momentum of the system and as well as the total energy of the system remains conserved.
Step 2 of 3</p>
Figure below show the diagrammatic representation of the situation. Here,initial direction of the cue ball is taken to be parallel to the side of the table. and is the angle made by the object ball and the cue ball after collision respectively as shown in figure below.
